Ramseier Group

What Ramseier Group does

Ramseier Group is a fourth-generation, family-owned Swiss construction holding company headquartered in Bern, founded in 1933 and operating five wholly-owned profit centers — Ramseier Bauunternehmung AG, Ramseier Integral AG, A. Reist Schreinerei AG, Ritter Bauunternehmung AG, and von Dach AG Bern — that together cover the full construction-services value chain from foundation to roof. Its service portfolio spans new construction, conversion and renovation, general contracting (Totalunternehmer mandates), facade construction, timber element and prefabricated construction, insulation, plastering, carpentry and joinery, steep-roof work, natural stone masonry, and photovoltaic installation. Project sizes disclosed range from CHF 75,000 private renovations to CHF 10.5 million total-contractor mandates (e.g., Villa Egghölzli), with notable institutional clients including Stadt Bern, Stadt Biel, the Bundesamt für Bauten und Logistik, PostFinance AG, and Halter AG.

The group's underlying technology is an integrated multi-trade delivery model that consolidates general contractor coordination (Ramseier Integral AG), specialized trades (facade/timber, plastering, carpentry, natural stone), and regional construction execution (Ritter Bauunternehmung AG) under a single brand and ownership umbrella. Differentiated technical capabilities include CNC-controlled stone milling for Bernese sandstone and other natural stones (von Dach AG Bern), prefabricated Holzelementbau (timber element construction) produced in controlled production halls, and energy-efficient facade systems engineered for low-energy, passive, or zero-energy building standards. The group holds ISO 9001 and Holzbau Plus certifications and is operationally active as of 2025 with new project announcements continuing into 2026.

Commercially, Ramseier Group operates a project-based revenue model with pricing determined per project via quote; revenue is recognized on completion and handover. Go-to-market is hybrid: enterprise and institutional sales (government, public-sector, and large real-estate clients) are managed directly through Geschäftsführer (division heads) and project managers, while private residential demand is generated through brand reputation, project references, community sponsorship, and architect/engineer referrals within the Bern and Seeland catchment. Customer segments include private Bauherren, institutional/public-sector clients, and architects/engineers, served exclusively through direct regional engagement with no digital self-serve or e-commerce channels.
